写在前面

前面写了一篇关于将.NET应用转换成Windows服务的方法，其实真正的目的是为了探索如何将Asp.Net Core Web Api 部署成Windows 服务。基于上一篇的基础，只需把创建 WebApplication 的代码放到 BackgroundService 的ExecuteAsync方法中即可。

其中比较重要的一个细节就是需要指定一下配置：

host.ConfigureAppConfiguration((hostingContext, config) => {
config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
config.AddEnvironmentVariables();
});

appsettings.json 的内容如下：

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "urls": "http://localhost:6001",
  "server.urls": "http://localhost:6001"
}

重点部分：

"urls": "http://localhost:6001",
"server.urls": "http://localhost:6001"

代码实现

using System.Runtime.InteropServices;
using System.Text.Json.Serialization;
using Microsoft.Extensions.Hosting;

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args)
    {
        var host = Host.CreateDefaultBuilder(args);
        //判断当前系统是否为windows
        if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
        {
            host.UseWindowsService();

        }

        host.ConfigureAppConfiguration((hostingContext, config) => {
            config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
            config.AddEnvironmentVariables();
        });

        return host.ConfigureServices((hostContext, services) =>
        {            
            services.AddHostedService<WebApp>();

        });
    }
}

public class WebApp: BackgroundService
{
    public void StartApp()
    {
        var builder = WebApplication.CreateSlimBuilder([]);

        builder.Services.ConfigureHttpJsonOptions(options =>
        {
            options.SerializerOptions.TypeInfoResolverChain.Insert(0, AppJsonSerializerContext.Default);
        });

        var app = builder.Build();

        var sampleTodos = new Todo[] {
            new(1, "Walk the dog"),
            new(2, "Do the dishes", DateOnly.FromDateTime(DateTime.Now)),
            new(3, "Do the laundry", DateOnly.FromDateTime(DateTime.Now.AddDays(1))),
            new(4, "Clean the bathroom"),
            new(5, "Clean the car", DateOnly.FromDateTime(DateTime.Now.AddDays(2)))
        };

        var todosApi = app.MapGroup("/todos");
        todosApi.MapGet("/", () => sampleTodos);
        todosApi.MapGet("/{id}", (int id) =>
            sampleTodos.FirstOrDefault(a => a.Id == id) is { } todo
                ? Results.Ok(todo)
                : Results.NotFound());

        app.Run();
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        StartApp();
    }
}

public record Todo(int Id, string? Title, DateOnly? DueBy = null, bool IsComplete = false);

[JsonSerializable(typeof(Todo[]))]
internal partial class AppJsonSerializerContext : JsonSerializerContext
{
